9 Claims.

My invention relates to tobacco pipes, and more particularly to aspecific type of tobacco pipe in which may be utilized a pre-formedtobacco load or cartridge.

Among the objects of my invention are: To provide a pipe and loadtherefor whereby the load may be cooled during the smoking thereof; toprovide a tobacco pipe designed to accurately position a pre-formedtobacco cartridge; to provide a pipe and cartridge therefor co-operatingto provide an air space between the cartridge and the pipe bowl; to'provide a tobacco cartridge containing a filter; to provide a means andmethod of flavoring tobacco; to provide a means for accuratelypositioning a tobacco cartridge in a smoking pipe; and to provide a pipeand cartridge therefor giving a cool smoke.

My invention possesses numerous other objects and features of advantage,some of which, together with the foregoing, will be set forth in 20 thefollowing description of specific apparatus embodying and utilizing mynovel method. It is therefore to be understood that my method isapplicable to other apparatus, and that I do not limit myself, in anyway, to the apparatus of the 25 present application, as I may adoptvarious other apparatus embodiments, utilizing the method, within thescope of the appended claims.

Referring-to the drawing:

Figure l is a view partly in section and partly in 30 elevation of oneform of my invention.

Figure 2 is a sectional view of one form of pipe and cartridge.

Figure 3 is a sectional view of another form of pipe and cartridge.

I am well aware of the fact that cartridges containing tobacco in acombustible wrapper have been used in the past, but in most cases suchcartridges have simply been used as a convenient means for loading apipe. I am also aware that 40 under certain circumstances cartridgeshave been inserted in pipes in such a manner that the bottom portion ofthe cartridge frictionally engages the lumen of the pipe at its lowerend only. presumably leaving an air space between a short 45 portion ofthe charge and the bowl of the pipe.

This latter form of cartridge, however, has not proved satisfactory inuse, inasmuch as it is necessary to press on the outer end of the chargein order to force the lower portion into supporting contact with thepipe bowl. The force necessarily used almost invariably splits thewrapper and the tobacco completely fills the bowl, eliminating any airspace.

I have, however, invented a unitary charge for insertion within a pipebowl in such a manner that when the pipe is properly made no force isnecessary to position the charge, and there will at all times be acomplete air space between the burning charge and the wall of the pipe.This air space allows air to circulate around the burning charge,prevents the bowl of the pipe from heating, and makes for a much coolersmoke than can be obtained in the ordinary pipe. Inasmuch as no pressureis placed upon the wrapper of the cartridge it does not break, butmaintains its relative position until the charge is consumed.

My invention also utilizes a filter in connection with the cartridge,and if the tobacco is to be flavored I place the flavor in the filter,not in the tobacco. In this latter manner I am able to utilize the sametobacco for a. large number of cartridges carrying different flavors,thus making for cheapness of assembly. My pipe construction insuresproper alignment of the cartridge.

Other advantages of my invention may be more readily understood bydirect reference to the drawing.

Figure 1 shows one preferred form of pipe embodying my invention. Thepipe has the customary mouthpiece l fastened to a stem 2 in the usualmanner, and it is of course obvious that any of the saliva collectingdevices may be used between the mouthpiece and stem.

I prefer to form my pipe with a split between bowl and stem, stemportion 3 being provided with threads 4 co-operating with bowl threads 5cut into a bowl 6, the outside of the pipe being smooth when assembled.

Thus, I have provided a pipe which carries two shoulders withinthesmoking chamber; a bowl shoulder 1 and a stem shoulder 8, which maybe utilized to clamp and position the periphery of a charge supportingflange, extending laterally from tobacco cartridge 9. This cartridge iswell illustrated in two modifications in Figures 2 and 3 In Figure 2, acup I0 is provided with the peripheral supporting flange H, and a bodypor-'. tion l2 provided with perforations [3 at the bottom thereof, thelatter perforations opening into stem chamber H. In this case the cupextends downwardly into the stem chamber l4, and the cup is filled withfilter material IS. The cup itself is preferably formed from an asbestosor other non-burning material, and likewise the filter material It: maybe of finely divided asbestos fiber or similar material so that it alsowill not burn.

A charge of pipe tobacco I6 is surrounded by a combustible wrapper [1,the latter extending into the cup and preferably cemented thereto sothat the charge I6 is supported by the cup in upright position.

To insert the cartridge 9 in the pipe all that is necessary to do is tounscrew the bowl from the stem, drop the charge in with the cup enddown, and re-screw the bowl on the stem. The periphery H of the cup isthus clamped tightly, holding the charge upright, and inasmuch as thecup side wall contacts the shoulder 8 it is obvious that the charge isalways centered. I prefer to make the charge of substantially lesserdiameter than the bowl interior, so that an air space I8 is providedbetween the bowl and the charge; and I prefer that this air space becomeincreasingly large as the end of the charge is approached although thisis not necessary, but increases the cooling effect. I also prefer thatno bowl material shall touch the burning tobacco, and therefore in thisparticular modification I have provided an air gap I9 between thelower-level of the charge i6 and the upper shoulder 1.

Another modification is shown in Figure 3. Here, the cup body is turnedupwardly, andinstead of projecting into chamber I4 it projects away fromchamber l4 and enlarges this chamber. In this case I omit the air spacel9 between the cartridge and the upper shoulder 1; and the uppershoulder 1, itself, serves to position the charge in a central position.In this case the filter material is not placed in the cup, but is placedbetween the bottom of the cup and the bottom of the charge, and issurrounded by the combustible wrapper I! instead of by the cup material.In this instance the tobacco charge l6 does not approach close to thebowl walls at any point, and therefore at no time during the smoking ofthe charge will the bowl be in contact with the burning tobacco.

It is to be noted that my improved cartridge and co-operating pipeassure the fact that a comparatively large air space shall always beleft between the burning charge and the bowl of the pipe; no pressure isneeded to force the cartridge in place, the charge being held solely byshoulders I and 8. No pressure is necessary on the outer end of thecharge, and therefore the combustible wrapper is never broken and thecharge is maintained in position until entirely smoked. After it iscompletely smoked the bowl is unscrewed, the cup and ash knocked out,and a new charge inserted.

Many smokers desire different flavors in their tobacco, and in mostcases such flavors are combined within the tobacco itself. If a largenumber of flavors is desired, diiferent lots of tobacco have to betreated, making the flavored tobacco expensive. With my improvedcartridge, however, I am able to utilize the same basic tobacco mixturein different cartridges, but I put the flavor to be given to the tobaccointo filter l5. Tobacco readily takes up flavor, and during shipment ofthe tobacco, the tobacco in each charge is permeated with the flavor inthe filter, and, in addition, during the smoking of the charge the smokeis drawn through the filter and becomes impregnated with the flavoringmaterial. I am thus able to supply the smoker with a large number offlavors at a minimum cost, and I have successfully flavored tobacco inthis manner with anise, menthol, walnut, maple, rose, apple etc. Theflavors, of course, may be used alone or in combination to suit thesmoker.

Summarizing, I have provided a compact cartridge comprising tobacco,wrapper, filter and flavoring material, together with a firm and solidmeans for supporting the cartridge in conjunction with clampingshoulders in a split bowl pipe. The charge is centered and held in thepipe by a special shoulder so that there is a complete air space aroundthe entire charge during the entire time of smoking. No pressure isnecessary to place the charge in the pipe, and the combustible wrapperof the cartridge is therefore never broken. A cool and flavored smoke istherefore obtained with no chance of the burning tobacco ever touchingthe bowl.

I may, however, desire to still further improve the coolness of thesmoke by providing in the 'bowl of the pipe adjacent the lower portionof the charge, air inlet apertures 20. The size and number of theseapertures are not important to my invention but they should besuflicient so that a draft is provided between the lower and upperportion of the bowl, and in order to equalize the draft, I prefer toposition these apertures circumferentially around the bowl. Furthermore,I increase the flow of air through the space l9 by directing theaperture bores at an angle so that any downward motion of the pipecauses air to pass along the sides of the burning charge. Inasmuch asthe pipe is usually in more or less continual motion, such motion aidsthe cooling by forcing the air past the charge in addition to thenatural draft created by the heat of the charge.
